CROSS REFERENCE TO RELATED APPLICATION

This application takes priority from and claims the benefit of ChinesePatent Application Serial No. 201910083072.X filed on Jan. 28, 2019 andChinese Patent Application Serial No. 201920147167.9 filed on Jan. 28,2019, the contents of which are herein incorporated by reference.

TECHNICAL FIELD

The present invention relates to the technical field of fitnessequipment, and in particular to a walking machine.

BACKGROUND

At present, due to environmental pollution such as automobile exhaustand smog, outdoor fitness has become more and more harmful. In addition,due to the increasing number of cars, motorcycles, mopeds, bicycles andother vehicles, it is increasingly difficult to find a suitable placefor people to exercise. In addition, outdoor fitness is also affected byweather such as rain, snow, fog, haze, sandstorm, etc. The fitnessexercise will inevitably be intermittent and cannot reach the continuityof fitness. Indoor fitness is gradually accepted and liked by peoplebecause it is not affected by the weather or limited by time.

Krauth Burns, German sports expert, pointed out that the impact on thesole of the foot is about 1-2 times of the body weight for every bigstep taken by ordinary people. Its impact on the sole of the foot isonly about ⅓ of that of jogging. The pressure on the corresponding kneejoint and ankle joint is also much smaller. If compared with fasterwalking, the pressure on the knee joint and ankle joint is much smaller.Under normal circumstances, walking will not cause serious knee jointand ankle joint injuries. In particular, the joints of the elderly beginto age, and the knee joint and ankle joints cannot bear the impactgenerated during walking. Running is not suitable for the elderly.Walking fitness is the best choice.

With the development of economy and the improvement of living standards,people begin to pay more and more attention to their own healthexercises, thus making fitness equipment increasingly popular in themarket. As the commonly used fitness equipment, consumers pay more andmore attention to and purchase walking machines. As shown in FIG. 1, theexisting domestic walking machine consists of a walking belt 1′, awalking board, a motor 2′, a roller 3′ and a frame 4′, and needs peopleto move on the walking belt 1′ when in use.

The applicant found that the existing walking machine has at least thefollowing technical problems.

The walking machine is low in overall safety and large in occupied spacesince the motor 2′ and the roller 3′ of the existing walking machine areexposed outside the frame 4′.
